Legal claims defining the scope of protection, as filed with the USPTO.
8. The wireless communications apparatus according to claim 7, wherein the receiver is further configured to detect the aperiodic TRS with a transmission power which has a fix relationship with a transmission power used for transmitting a SSB in the same cell.
9. The wireless communications apparatus according to claim 7, wherein the receiver is further configured to receive an indication of a transmission power of the aperiodic TRS, wherein the indication comprises a power value or a power offset to a transmission of a SSB in the same cell.
10. A base station apparatus comprising a transmitter, wherein the transmitter is configured to send a message configuring a tracking reference signal (TRS) resource for SCell activation for configuring a TRS for SCell activation as a time-frequency synchronization signal, wherein the TRS resource is an aperiodic TRS resource, wherein the SCell is activated by a MAC CE and the aperiodic TRS is triggered by a MAC CE, and wherein the aperiodic TRS is triggered in slot n1 and the aperiodic TRS is transmitted in slot n1+X, wherein X is an offset configured by a RRC message or defined by a protocol.
11. The base station apparatus according to claim 10, wherein the transmitter is further configured to transmit the aperiodic TRS with a transmission power which has a fix relationship with a transmission power used for transmitting a SSB in the same cell.
12. The base station apparatus according to claim 10, wherein the transmitter is further configured to indicate a transmission power of the aperiodic TRS, wherein the indication comprises a power value or a power offset to a transmission of a SSB in the same cell.
